I was reading some threads elsewhere and stumbled upon "chemiwood"

It's a polyuretahne modelling board used for rapid prototyping and model making. It's dimensionally stable and inert. Dense uniform composition and flatness. Machines better than timbers with no material break out. Can be milled and turned, sands quickly by machine or hand.

It's a mixture of resins, fillers and plastics.

It also goes by the names model board or model lab board.

Does anyone have any experience of using this stuff? It sounds pretty expensive and isn't supplied in smaller quantities for modellers, seems to be in 4ft x 1ft sheets in a variety of grades and densities.

Sounds ideal for machining small model components.

I've found this supplier:

Not really sure which grade would suffice though, gets a little technical with details about it's flexural strength?? and Coefficients of Thermal Expansion...
